854 AUSTRALIAN COLEOPTERA, WITH DESCRIPTIONS OF NEW SPECIES, 



The puncturation is on the whole rather uniform over the 

 entire upper surface, but l^ecomes gradually a little finer and 

 less close from the clypeiis hindward to the apex of the elytra ; 

 the scales are small, elongate, and hair- like, and are rather closely 

 distributed, but not very conspicuous. The clypeus is very 

 strongly emarginate in front, the length from the base of tlu» 

 emargination to the clypeal suture being scarcely half the greatest 

 length of the clypeus. The prothorax is about half again as wide 

 as it is long down the middle, its base being less than half again 

 as wide as its front margin. The elytra are scarcely costate, the 

 indications of costas appearing as mere irregularities of the sur- 

 face which do not disturl) the sculpture (in L. Darvoini and 

 Rotliei the costse are devoid, or very nearly so, of puncturation). 

 On the underside the sculpture is of the same character as on 

 the upper, but the puncturation is less rugose and more sparing, 

 and the scales less hair-like. The teeth on the external edge of 

 the front tibi;e resemble the same in L. Rotliei, all being very 

 sharp, the upper one much smaller than the lower two. The two 

 specimens l)efore me piesent no notable character likely to be 

 sexual unless it be that the elytra of one are somewhat dilated 

 behind the middle, while those of the other are narrower and 

 more parallel. 



The small size of this species will distinguish it from the three 

 species previously described ; the very small hair-like scales of its 

 upper "surface and almost non-costate elytra also are distinctive.
